Frequently Asked Questions
Common questions about tiny homes, modular homes, and prefab builders in Australia.
Costs and Pricing
How much does a tiny house cost in Australia?
Most turnkey tiny houses in Australia fall between $70,000 and $180,000+, depending on size, spec level, and whether it is on wheels or a fixed build. Shell-only builds start lower, around $50,000 to $70,000. Site works, delivery, and utility connections are usually additional.
How much does a modular home cost in Australia?
Modular homes typically range from $2,000 to $4,500 per square metre for the building itself. A basic one-bedroom transportable cabin starts around $150,000 all-in, while a large multi-module home can exceed $500,000 once you factor in transport, craning, and site works.
What costs are not included in a builder quote?
Most builder quotes exclude delivery and craning, site preparation (foundations, levelling), utility connections (power, water, sewer), council and compliance fees, and insurance. On a straightforward suburban block these extras might add $10,000 to $30,000. On a rural site with no existing services, it can be significantly more.
Can I get finance for a tiny house?
Yes, but the pathway depends on how your tiny home is classified. Personal loans work for smaller builds. Home loans are possible if the dwelling is on owned land and meets valuation requirements. Asset or chattel finance suits some transportable setups. Using existing home equity is often the simplest path. Talk to a broker who has handled non-standard dwellings.
Approvals and Legality
Do I need council approval for a tiny house in Australia?
Almost certainly, if you plan to live in it full-time. The type of approval depends on your state, your council, and how the dwelling is classified. Fixed tiny homes on proper foundations generally have a clearer approvals pathway than tiny houses on wheels. Always confirm with your local council before committing.
Are tiny houses on wheels legal in Australia?
THOWs sit in a grey area between vehicle and dwelling. Transport regulations govern road movement (width, height, weight limits), while council planning rules control placement and occupancy. Some councils are pragmatic, others are strict. Legality depends entirely on where you put it and how you use it.
What is the difference between a DA and a CDC?
A Development Application (DA) is a full planning assessment submitted to council. A Complying Development Certificate (CDC) is a faster pathway available in NSW and some other states if your build meets specific criteria. CDCs go through a private certifier rather than council, making them quicker and more predictable.
Do I need approval for a granny flat?
Yes, but the pathway is usually clearer than for a tiny house. In NSW, secondary dwellings up to 60 square metres on lots over 450 square metres can go through complying development. Other states have their own provisions. Granny flats have a defined place in planning law, which generally makes approvals more straightforward.
Choosing a Builder
How do I compare tiny home builders?
Get quotes from 3 to 5 builders and compare them side by side. Focus on: total delivered price (not just base price), written inclusions and exclusions lists, insulation and glazing specs, warranty terms, and realistic timelines. The cheapest base price is rarely the cheapest total cost.
What should I ask a tiny home builder before committing?
The most important questions cover compliance (what standards do they build to, and can they provide documentation), what exactly is included in the quote, warranty details, delivery constraints for your site, timeline from deposit to delivery, and whether you can speak with recent customers.
Should I visit a builder factory or display?
Yes, if you can. Photos cannot tell you about build quality, finish details, or how a space actually feels at full scale. An hour walking through a display model or factory tour is worth weeks of browsing websites.
What is the difference between modular, prefab, and kit homes?
Modular homes are built as complete modules in a factory and assembled on site. Prefab is a broader term covering any factory-built element (panels, pods, modules). Kit homes are a set of materials supplied for on-site assembly, often by an owner-builder. The key question is: how does it arrive on site, and what work remains?
Types and Features
What is the difference between a tiny house and a granny flat?
A granny flat is a secondary dwelling on an existing residential lot, with a defined place in planning law. A tiny house is a broader term that could mean a THOW, a cabin, or a small modular build. Granny flats have clearer approvals pathways and tend to hold property value better. Tiny houses offer more flexibility and mobility.
Can I go off-grid with a tiny house?
Yes. Most off-grid setups use solar panels with battery storage for power, rainwater tanks with filtration for water, and composting or cassette toilets for waste. A typical off-grid package adds $15,000 to $40,000 to the build cost. The key is planning the systems together with the build, not adding them as an afterthought.
How big is a typical tiny house?
Most tiny houses on wheels are 6 to 10 metres long and around 2.5 metres wide (to stay within road transport limits). Fixed tiny homes and modular builds can be wider. Anything over 10 metres or multi-module starts to feel closer to a small one-bedroom unit.
